Application filed June 7, 1921.

To all whom it may concern-.-

Be it known that we, Emma L. Sonormonnr: and lVmLriir H. BoUrnLLn, citi Zens of the United States, residing at Southbridge and Sturbridge, respectively, in the county of -Worcester and State of Massachusetts, have invented certain new and useful Improvements in Ophthalmic Mountings, of which the following is a specification.

lhis invention relates to improvements in ophthalmic mountings, being a continuation in part of our application filed Decemher 8, 1920, Serial Number i29,183.

The principal object of the present invention is the provision of an improved type of composition or non-metallic frame wlnch shall present a neat, novel and ornamental appearance, forming an improvement over anything previously known in this respect.

A further object of the present invention is the provision of a construction in which the parts shall be so united as to reduce the normal pupillary width of frames of this character, rendering the mounting more satisfactory both from a viewpoint of appearance and from a point of undesirable lateral projections and furthermore in which concealed or inconspicuous metallic bracing members shall be provided to prevent expansion or displacement of the bent temple engaging lugs which render the re duced width of the frame possible.

Another object of the invention is the provision of a mounting in which the temple front shall be of smooth and unbroken form, and in which the hinged joints for the frame shall be disposed in inconspicuous position concealed when the mounting is viewed from the front, and unsightly lateral projections affording hinge connections orattachments shall be eliminated.

Other objects and advantages of our improved construction should be readily apparent by reference to the following specification taken in connection with the accompanying drawings, and it will be understood that we may make any modifications in the specific details of construction shown and described within the scope of the appended claims without departing from or exceeding the spirit of the invention.

ment from that particularly illustrated in connection with Figure 11.

In the drawings, the numeral 1 designates a bridge or nose engaging portion of an ophthalmic mounting, and the numeral 2 the lens receiving frames or eyes. These parts have been illustrated as formed from composition or non-metallic material, such as Xylonite, shell, orthe like. As is particularly brought out in connection with the original application of which this is a division, the bridge and lens frames are preferably formed from separate parts of material and adjustably connected as by the metal loops 3, particularly illustrated in Figure 11. This, however, forms no part of our present-invention, since if desired the bridge and lens receiving frames may be formed from a single piece of material.

In frames of this type, that is, the heavy shell or Xylonite form, prior to our invention it has been customary to form the eyes with laterally extending lugs of appreciable size, preferably split so that the temple might be hinged therebetween. This construction has laterally extended the temples considerably beyond the edgeof the lenses and contrary to the usual principles followed in' frame fitting, in which the temples are disposed as near as possible up to the lenses and are then found to most satisfactorily comply with the requirements of the average face. These lugs, however, have been unsightly, have increased the over all liable to catch on the hair or clothing of the wearer and cause the glasses to become broken, and interfere with the general utility and desirability of the frame.

in carrying out our invention in place of making use of such laterally extending lugs, we form the frame with slight lug portions 12, which in place of projecting laterally are rearwardly curved, as clearly brought out in Figure ll of the drawings. This rearward curving forms a substantially conrealed space as at 13 to receive the hinge plate 14, preferably secured to the front at two or more points, as by the rivets or securing devices 6 and 7, one of which is secured to the front of theframe near the lens receiving groove, and the other near the terminus of the lug.

The advantage of this form of attachment is that the hinge plate itself is curved to conform to the shape of the inner face of the lug and when so attached serves to hold the lug in its curved position and prevent any straining or flattening out of the same under varying climatic or other conditions. A second hinge plate or portion 15 is suitably hinged to. the first member and connected. to the temple 16. With this form of construction the hinge is concealed. from view when the mounting is on the face and substantially concealed when the mounting is folded, the lug folding around and having its terminus in such position that the temple forms a substantially rearward continuation thereof and the end of the heavy temple in no wise shows from the front;

In Figure IV we have shown another form of our invention, in which the curved plate 21 is secured to the lug portion 12 of the frame and serves to carry the cap mom bers 22having the groove 23in which rides the plate 2st carried by the second hinged section '25 on the temple 26. This plate portion 2% is of arcuate form to slide around in the groove,'thus forming a connection in which there is no turning movement on the screw 27. We have found this hinge very satisfactory as causing the temple end to butt against the lug 12 and prevent liability of loosening of the securing screw as the temple is moved.

lVe claim:

1. An ophthalmic mounting including a non-metallic front for the mounting having integral rearwardly curving endpicce' portions and a curvedmetalhe bracing member secured to each of said end-piece portions to preventstraightening thereof. 7

2-. An ophthalmic mounting having a non metallic lens receiv ng portion formed with a rearwardly curving endpiece lug and a metal hlnge member having a curved portion inter-engaged with the lug to prevent accidental straightening thereof.

3. An ophthalmic mounting including a non-metallic rearwardly curving end-piece lug and a metal hinge member associated therewith having a curved portion int-en engaged with the lug to prevent'accidental straightening thereof, said metallic member terminating in a pivot eye, and a temple pivotally secured to the eye and forming substantially a continuation of the rearwardly curving lug.

4-. An ophthalmic mounting including a non-metallic lens receiving frame having a rearwardly curving lug integral therewith and a metallic fitting for the mounting having a curved portion interiorly fitting and secured to the lug and adjacent lens receiving frame to retain the parts in angnlarly disposed relation.

5. A combination frame including a rearwardlycurving composition end piece'lug, a co-extensive curved metal attaching portion carried by the lug and holding the same in curved position, and a projecting pivot eye carried by said metal member.

' 6. A device of the eluding composition-lens receiving frames hzwing rearwardly curving composition lugs at the outer sides thereof and metallic hinge connections in the form of plate like mom bers havingtheir greater width corresponding to that of the lugs, said plate like 111U1- bers havingcurved portions interengaged with the lugs to retain the lugs in their curved position, and having temple pivot connections, the plates being so disposed as to beinvisible vhen the mountingisviewed from the front.
